Antibiotics have been a critical public health tool since the discovery of Penicillin in 1928, saving the lives of millions of people around the world. In developing country like ours, where the burden of treatable disease is very high and access to health facilities and laboratories is difficult, a...ntibiotics have long acted as miracle drugs. Today, however, the emergence of drug
resistance in bacteria is reversing the miracles of the past eighty years, with drug choices for the treatment of many bacterial infections becoming increasingly limited, expensive, and in some cases, nonexistent. Diseases previously regarded as relatively easy to manage are much harder to treat as doctors must use “last-resort” drugs that are more costly, take longer to work
and are often unavailable or unaffordable in developing countries. Moreover, regular prescription of antibiotics, random treatment, over the counter sales, inadequate dosage, inclusion of antibiotics in animal feeds and agriculture has contributed equally to emergence of antibiotics resistance as silent epidemic within the country.

The current document is anupdate of the guidelines developed by the EUCAST subcommittee on detection of resistance mechanisms. The EUCAST Steering Committee has carried out the current update. The document has been developed mainly for routine use in clinical laboratories and doesnot cover technical... procedures for identification of resistance mechanisms at a molecular level by reference or expert laboratories. However, much of the content is also applicable tonational reference laboratories. Furthermore, it is important to note that the document does not cover screening for asymptomatic carriage (colonization) of multidrug-resistant microorganismsor direct detectionof resistancein clinical samples.

In 2009, WHO’s Second International Conference on Buruli Ulcer Control and Research resolved to strengthen the capacity of national laboratories to confirm cases of the disease, but advised that “efforts are still needed to develop simple diagnostic tools usable in the field as well as disabilit...y prevention methods”.
In 2013, WHO and the Foundation for Innovative New Diagnostics convened a meeting of Buruli ulcer experts in Geneva, Switzerland (9) at which two priority unmet needs in diagnosis were identified:
a diagnostic test for early detection of Buruli ulcer in symptomatic patients with sufficient positive predictive value to put patients on appropriate treatment; and
a screening test at the primary health care or community level for symptomatic patients with ulcer

-rence Laboratories (NRLs) across Africa.
Africa CDC and APHF are coordinating a continental initiative to maximize the benefits of molecular approaches and pathogen genomics for more effective
outbreak preparedness, prevention, response, and for the control and elimination of endemic diseases in Africa. One of Africa CDC’s flagship initiative is the Africa
Pathogen Genomics Initiative (Africa PGI), a partnership that aims to strengthen laboratory systems and enhance genomic surveillance by equipping the continent’s
public health institutions with the tools, training, and data infrastructure.
About the Project
In 2023, 166 outbreaks and public health events were reported in Africa. This calls for a resilient laboratory systems for timely detection and reporting of current and future outbreaks. This project aims to scale up molecular diagnostic and genomic sequencing-based detection and characterization of outbreaks.
Africa CDC is working with Member States to develop guidance, diagnostic algorithm, training and capacity building to enable outbreak detection, and reporting to inform public health response.

En enero de 2020, el agente etiológico responsable de un grupo de casos de neumonía grave en Wuhan, China, fue identificado como un nuevo betacoronavirus (2019-nCoV), distinto del SARS-CoV y MERS-CoV (1) (2) (3). La secuencia genómica completa de este nuevo agente está disponible y se han desarr...ollado diferentes protocolos de detección, aunque aún no se han validado por completo. Sin embargo, a la luz de la posible introducción de un caso sospechoso relacionado con el 2019-nCoV en la Región de las Américas, la Organización Panamericana de la Salud / Organización Mundial de la Salud (OPS / OMS) recomienda a los Estados Miembros garantizar su identificación oportuna, el envío de las muestras a laboratorios Nacionales o de referencia y la implementación del protocolo de detección molecular para 2019-nCoV, según la capacidad del laboratorio.
Hasta la fecha, no es completamente claro el potencial patogénico ni la dinámica de transmisión del 2019nCoV. Por esta razón y a la luz del conocimiento de otros virus similares (MERS-CoV, SARS-CoV), es necesario mantener y fortalecer las medidas de bioseguridad y elementos de protección personal para el trabajo con muestras sospechosas de infección con patógenos respiratorios.
